Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474888, here are decompositions:

59 + 31474829 = 31474888
167 + 31474721 = 31474888
197 + 31474691 = 31474888
311 + 31474577 = 31474888
317 + 31474571 = 31474888
491 + 31474397 = 31474888
569 + 31474319 = 31474888
587 + 31474301 = 31474888

Showing the first eight; more decompositions exist.
